A new method to produce large, monolayer single-crystal-like graphene films more than a foot long relies on harnessing a “survival of the fittest” competition among crystals.
For Juan Carlos Idrobo, the scientist’s journey is like taking a test that is only two pages long. You start reading the first page, but you don’t understand any of the questions.
Oak Ridge National Laboratory researchers have directly written high-purity metallic structures narrower than a cold virus—which could open nanofabrication opportunities in electronics, drug delivery, catalysis and chemical separations.
Material surfaces and interfaces may appear flat and void of texture to the naked eye, but a view from the nanoscale reveals an intricate tapestry of atomic patterns that control the reactions between the material and its environment.
